Ukusungulwa kanye nokuvela komshini wokwenza amabhodlela we-IS onqumayo
Ekuqaleni kwawo-1920, umanduleli wenkampani Buch Emhart e Hartford wazalwa umshini wokuqala determinant ibhodlela ukwenza (Individual Isigaba), okuyinto yahlukaniswa yaba amaqembu amaningana ezimele, iqembu ngalinye Lingakwazi ukumisa futhi ushintshe isikhunta ngokuzimela, kanye nokusebenza kanye ukuphathwa kulula kakhulu.Kungumshini wokwenza ibhodlela we-IS onezingxenye ezine.Isicelo selungelo lobunikazi safakwa ngo-August 30, 1924, futhi asizange sivunyelwe kwaze kwaba ngo-February 2, 1932. .Ngemuva kokuthi imodeli iqale ukudayiswa ngokuhweba ngo-1927, yathola ukuthandwa okubanzi.
Selokhu kwasungulwa isitimela esizihambelayo, sidlule ezigabeni ezintathu zokugxuma kwezobuchwepheshe: (Izikhathi Ezi-3 Zobuchwepheshe kuze kube manje)
1 Ukuthuthukiswa komshini wezinga we-IS oyimishini
Emlandweni omude kusukela ngo-1925 kuya ku-1985, umshini wokwenza ibhodlela wohlobo lwerowu wawuwumshini omkhulu embonini yokwenza amabhodlela.Idrayivu yesigubhu esisebenza ngomshini/i-pneumatic cylinder (Timing Drum/Pneumatic Motion).
Lapho isigubhu esiwumshini simataniswa, njengoba isigubhu sizungezisa inkinobho yevalvu esigubhini sishayela ukuvuleka nokuvalwa kwevalvu kuMechanical Valve Block, futhi umoya ocindezelwe ushayela isilinda (Isilinda) ukuze siphindaphinde.Yenza isenzo siphelele ngokwenqubo yokubumba.
2 1980-2016 Okwamanje (namuhla), isitimela sesikhathi se-elekthronikhi i-AIS (I-Advantage Individual Section), isilawuli sesikhathi sikagesi/i-pneumatic cylinder drive (Ukulawula Ugesi/I-Pneumatic Motion) sasungulwa futhi safakwa ngokushesha ekukhiqizeni.
Isebenzisa ubuchwepheshe be-microelectronic ukulawula izenzo zokwakheka ezifana nokwenza amabhodlela kanye nesikhathi.Okokuqala, isignali kagesi ilawula i-valve ye-solenoid (i-Solenoid) ukuze ithole isenzo sikagesi, futhi inani elincane lomoya ocindezelwe lidlula ekuvuleni nasekuvaleni kwe-valve ye-solenoid, futhi isebenzisa le gesi ukuze ilawule i-sleeve valve (I-Cartridge).Bese ulawula ukunyakaza kwe-telescopic yesilinda sokushayela.Okusho ukuthi, okuthiwa ugesi ulawula umoya oncishanayo, futhi umoya oncishanayo ulawula umkhathi.Njengolwazi lukagesi, isignali kagesi ingakopishwa, igcinwe, ivalwe futhi ishintshwe.Ngakho-ke, ukubonakala komshini wesikhathi we-electronic AIS ulethe uchungechunge lwezinto ezintsha emshinini wokwenza amabhodlela.
Njengamanje, iningi lebhodlela lengilazi kanye nezimboni zasekhaya nakwamanye amazwe zisebenzisa lolu hlobo lomshini wokwenza amabhodlela.
3 2010-2016, umshini womugqa we-servo ogcwele i-NIS, (i-New Standard, i-Electric Control/Servo Motion).Ama-Servo motors asetshenziswe emishinini yokwenza amabhodlela kusukela cishe ngo-2000. Aqala ukusetshenziswa ekuvuleni nasekuhlanganiseni amabhodlela emshinini wokwenza amabhodlela.Umgomo wukuthi isignali ye-microelectronic ikhuliswa yisekethe ukuze ilawule ngokuqondile futhi ishayele isenzo se-servo motor.
Njengoba i-servo motor ingenayo i-pneumatic drive, inezinzuzo zokusebenzisa amandla aphansi, akukho msindo nokulawula okulula.Manje isithuthuke yaba umshini ogcwele wokwenza ibhodlela le-servo.Kodwa-ke, ngenxa yeqiniso lokuthi awekho amafekthri amaningi asebenzisa imishini yokwenza amabhodlela e-servo egcwele e-China, ngizokwethula okulandelayo ngokolwazi lwami olungajulile:
Umlando kanye Nokuthuthukiswa kwe-Servo Motors
Maphakathi kuya ekupheleni kwawo-1980, izinkampani ezinkulu emhlabeni zazinohlu oluphelele lwemikhiqizo.Ngakho-ke, i-servo motor ikhuthazwe ngamandla, futhi kunezinkambu zokusetshenziswa eziningi ze-servo motor.Uma nje kunomthombo wamandla, futhi kunesidingo sokunemba, ngokuvamile kungase kuhilele i-servo motor.Njengamathuluzi omshini wokucubungula ahlukahlukene, okokuphrinta, okokufaka, okokusebenza kwendwangu, okokusebenza kwelaser, amarobhothi, imigqa ehlukahlukene yokukhiqiza ezenzakalelayo nokunye.Izisetshenziswa ezidinga ukunemba kwenqubo ephezulu uma kuqhathaniswa, ukusebenza kahle kokucubungula nokuthembeka komsebenzi zingasetshenziswa.Emashumini amabili eminyaka adlule, izinkampani zakwamanye amazwe ezikhiqiza umshini wokukhiqiza amabhodlela nazo zamukele ama-servo motors emishinini yokwenza amabhodlela, futhi zisetshenziswe ngempumelelo emgqeni wangempela wokukhiqiza wamabhodlela engilazi.isibonelo.
Ukwakhiwa kwe-servo motor
Umshayeli
Inhloso yokusebenza ye-servo drive ngokuyinhloko isekelwe emiyalweni (P, V, T) ekhishwe isilawuli esiphezulu.
I-servo motor kufanele ibe nomshayeli ukuze ijikeleze.Ngokuvamile, sibiza i-servo motor kuhlanganise nomshayeli wayo.Iqukethe i-servo motor ehambisana nomshayeli.Indlela evamile yokulawula umshayeli we-servo motor ye-AC ngokuvamile ihlukaniswe yaba izindlela zokulawula ezintathu: i-position servo (P command), i-speed servo (umyalo we-V), ne-torque servo (umyalo we-T).Izindlela zokulawula ezivame kakhulu i-servo yesikhundla ne-speed servo.Servo Motor
I-stator ne-rotor ye-servo motor yakhiwe ngozibuthe unomphela noma amakhoyili ensimbi.Ozibuthe abangapheli bakhiqiza insimu kazibuthe kanti amakhoyili ensimbi azophinde akhiqize amandla kazibuthe ngemva kokunikwa amandla.Ukusebenzisana phakathi kwendawo kazibuthe ye-stator kanye ne-rotor magnetic field kukhiqiza i-torque futhi ijikeleze ukushayela umthwalo, ukuze kudluliselwe amandla kagesi ngesimo senkundla kazibuthe.Iguqulelwe kumandla okusebenza, i-servo motor iyazungeza uma kukhona okokufaka kwesignali yokulawula, futhi iyama uma kungekho okokufaka kwesignali.Ngokushintsha isignali yokulawula kanye nesigaba (noma i-polarity), isivinini nesiqondiso se-servo motor singashintshwa.I-rotor ngaphakathi kwe-servo motor iyizibuthe unomphela.Ugesi wezigaba ezintathu we-U/V/W olawulwa umshayeli wenza inkambu ye-electromagnetic, futhi i-rotor izungeza ngaphansi kwesenzo salo mkhakha kazibuthe.Ngaso leso sikhathi, isignali yempendulo yesishumeki esifika nenjini sithunyelwa umshayeli, futhi umshayeli uqhathanisa inani lempendulo nenani eliqondiwe ukuze alungise i-angle yokujikeleza ye-rotor.Ukunemba kwe-servo motor kunqunywa ukunemba kwesifaki khodi (inombolo yemigqa)
Isifaki khodi
Ngenhloso ye-servo, i-encoder ifakwe i-coaxially ekuphumeni kwemoto.Injini nesishumeki sizungeza ngokuhambisanayo, nesishumeki siphinde sizunge lapho injini isizungeza.Ngesikhathi esifanayo sokujikeleza, isignali yokufaka ikhodi ibuyiselwa kumshayeli, futhi umshayeli uyahlulela ukuthi isiqondiso, isivinini, indawo, njll. ye-servo motor ilungile ngokuya ngesignali yesishumeki, futhi ulungise ukuphuma komshayeli. ngokufanele.I-encoder ihlanganiswe ne-servo motor, ifakwe ngaphakathi kwe-servo motor
Isistimu ye-servo iwuhlelo lokulawula oluzenzakalelayo oluvumela amanani alawulwayo okukhiphayo okufana nendawo, umumo, kanye nesimo sento ukulandela izinguquko ezingafanele zethagethi yokokufaka (noma inani elinikeziwe).Ukulandela umkhondo wayo we-servo ikakhulukazi kuncike kuma-pulse ukuze kubekwe indawo, okungaqondwa ngokuyisisekelo ngale ndlela elandelayo: i-servo motor izozungeza i-engeli ehambisana ne-pulse lapho ithola ukushaya kwenhliziyo, ngaleyo ndlela ibone ukufuduka, ngoba isishumeki se-servo motor sibuye sijikeleze, futhi inamandla okuthumela Umsebenzi we-pulse, ngakho-ke njalo lapho i-servo motor izungeza i-engeli, izothumela inombolo ehambisanayo yama-pulses, ehambisana nokushaya okutholwe yi-servo motor, futhi ishintshisane ngolwazi nedatha, noma iluphu evaliwe.Mangaki ama-pulse athunyelwa ku-servo motor, futhi mangaki ama-pulse atholwa ngesikhathi esifanayo, ukuze ukujikeleza kwe-motor kulawulwe ngokunembile, ukuze kuzuzwe ukuma okunembile.Ngemuva kwalokho, izojikeleza isikhashana ngenxa ye-inertia yayo, bese ima.I-servo motor kufanele ime lapho ima, futhi ihambe lapho kuthiwa iyahamba, futhi impendulo ishesha kakhulu, futhi akukho ukulahlekelwa kwesinyathelo.Ukunemba kwayo kungafinyelela ku-0.001 mm.Ngesikhathi esifanayo, isikhathi sokuphendula esiguquguqukayo sokusheshisa nokwehliswa kwesivinini se-servo motor futhi sifushane kakhulu, ngokuvamile phakathi kwamashumi ama-millisecond (isekhondi elingu-1 lilingana namamillisecond angu-1000)Kukhona iluphu evaliwe yolwazi phakathi kwesilawuli se-servo nomshayeli we-servo phakathi isignali yokulawula kanye nempendulo yedatha, futhi kukhona isignali yokulawula kanye nempendulo yedatha (ethunyelwe kusukela kusishumeki) phakathi komshayeli we-servo kanye ne-servo motor, futhi ulwazi phakathi kwabo lwakha iluphu evaliwe.Ngakho-ke, ukunemba kokuvumelanisa kokulawula kuphezulu kakhulu
